Gulfstream Aerospace has just announced the new G650ER. An ultra-long-range aircraft, the G650ER can travel up to 7,500 nautical miles (13,890 km) at a speed of Mach 0.85, or up to 6,400 nm (11,853 km) at the higher operating speed of Mach 0.90. This is an increase in range of up to 500 nm (926 km) over the original G650.
Earlier this year, a Gulfstream G650ER was flown 6,947 nm (12,866 km) from Los Angeles International Airport to Tullamarine Airport in Melbourne, Australia, at an average speed of Mach 0.86. This flight was accomplished with fuel reserves well in excess of the National Business Aviation Associations (NBAA) instrument flight rules (IFR) requirements and took 14 hours and 58 minutes into head winds of up to 13 knots.
